Nutrition Management Strategies for the Adaptation of Cull Beef Heifers to Feedlot
Providing diets with high roughage in the first days of confinement is the common way of adapting beef cattle to intensive production. However, it is possible to offer the final finishing diet from the first day of adaptation. Our objective was to compare a traditional adaptation protocol, in which animals received a diet with a higher proportion of ...

Heteroskedasticity for weaning weight of Charolais-Zebu crossbred calves
The objective of the present study was to analyze models with genetic and/or residual heteroskedasticity for genetic evaluation of the weaning weight of Charolais-Zebu crossbred calves. Weaning weight data from 56,965 crossbred calves were analyzed using

ABSTRACT Genetic progress of breeding programs is highly dependent on the size of reference populations and the relatedness between reference populations and selection candidates. Many reasons can lead a population to split into several subpopulations (sanitary, physiological, political reasons, etc.).

Genetic Heterogeneity of Residual Variance for Foot Score Traits in American Angus Cattle
ABSTRACT Foot conformation is one of the main breeding goals in recent beef cattle breeding programs because it directly affects productivity, economic losses, animal welfare and longevity. Genetic heterogeneity of residual variance can be used to improve production uniformity in animal breeding programs because recent studies have shown that residual ...

ABSTRACT Mature cow size, often defined by mature cow weight (MWT), height (MHT) and body condition score (BCS), is crucial to cow‐calf profitability, maintenance efficiency and reproductive performance. Although MWT and MHT are often included in national cattle evaluations by many breed organisations, BCS adjustments are applied less consistently ...

Genetic group and heterosis on morphometric measurements during the growth of male beef cattle
In the present study, the effects of genetic group and heterosis on body measurements of purebreds (Charolais - C and Nellore - N), first-generation crossbreds (G1) (1/2C1/2N and 1/2N1/2C), and second-generation crossbreds (G2) (3/4C1/4N and 3/4N1/4C ...
